Definitions

  • This invention relates to the field of rotary drive apparatus for rotating substantially cylindrical members such as pipe, tubing, and casing.
  • the present invention provides an improved rotary drive apparatus for applying rotational torque to a cylindrical member.
  • One improvement is the incorporation of front rollers having freely rotating flanges.
  • Another improvement is the provision of reaction rollers.
  • a conventional rotary drive apparatus having a body structure or housing including a recess to receive said cylindrical member, a drive wheel, a plurality of idler wheels, an endless loop trained around the drive wheel and the idler wheels forming a bight in the recess, said body structure including at least one jaw, the jaw bearing at least one of said idler wheels and positioned adjacent said recess, and said jaw being adjacent the recess and pivotable between an open position and a closed position.
  • an object of the present invention to provide an improved rotary drive apparatus for applying rotational torque to a cylindrical member through the provision of front rollers having freely rotating flanges.
  • a further object of the present invention is the provision of such an improved rotary drive apparatus having reaction rollers incorporated into it such that the reaction rollers react against the casing to reduce the friction losses due to toppling of the casing.
  • the incorporation of such reaction rollers produces a significant increase in torque and eliminates or reduces vibration.
  • FIG. 1 is a plan view of a rotary drive apparatus
  • FIG. 2 is a side elevation view of the rotary drive apparatus
  • FIG. 3 is a cross-sectional view taken along line 3--3 of FIG. 1.
  • a casing tong comprises a hydraulic motor 10 controlled by a control valve 12 and driving a sprocket wheel 14 through a gearbox 16.
  • the drive sprocket 14 is mounted in a housing or support 18 which provides a frame supporting the gearbox and motor and also containing idler rollers 20, 22, 24 and 26.
  • Idler rollers 20 and 22 are mounted on opposite sides of a recess 28 in the housing 18.
  • Jaws 30 and 32 are mounted on the housing 18 for pivotal movement about the same axes as the rollers 20 and 22 respectively.
  • the jaws 30 and 32 carry drive rollers 34 and 36 respectively and are pivotable between open positions in which a casing section such as 38 may be inserted in the recess 28 between the separated drive rollers 34 and 36, and closed positions, as shown in the drawings, in which the rollers 34 and 36 are brought adjacent each other.
  • Any suitable latch 40 preferably an automatic latch, is provided for retaining the jaws 30 and 32 in the closed position.
  • rollers 24 and 26 are mounted at the opposite end of the casing tong from the recess 28 on opposite sides of the drive sprocket 14 and an endless loop of chain 42 is trained around the idler rollers 20, 22, 24, 26, and around drive rollers 34 and 36, with a re-entrant bight 44 between the drive rollers 34 and 36 extending into the recess 28 for receiving and embracing the casing 38 and with a further re-entrant bight 46 between the rollers 24 and 26 trained round the drive sprocket 14.
  • the rollers 24 and 26 are mounted on the shafts such as 75 and 77 in the housing 18, the shafts being mounted on pistons of respective hydraulic rams 48 and 50 preferably positioned inside the housing and which are independently controllable by means of control valves (not shown) to displace the rollers 24 and 26 in the housing 18 generally towards and away from the idler rollers 20 and 22 respectively so as to lengthen or shorten the bight 44.
  • control valves not shown
  • the size of the bight 44 can be adjusted to suit casing diameter.
  • Reaction rollers 60 and 62 are rotatably mounted in the jaws 32 and 30, respectively, and are disposed so that their flanges--flanges 61 and 63 of reaction roller 60, as shown in FIG. 3 and flanges (not shown) of reaction roller 62--contact the outer surface of the cylindrical member to be rotated.
  • front roller 36 is rotatably mounted in jaw 32.
  • Flanges 35 and 37 are freely rotatable and mounted around shaft 39 of front roller 36 and are secured, respectively, by nuts 80 and 81.
  • Reaction roller 60 having fixed flanges 61 and 63 is rotatably mounted within jaw 32 and secured by nuts 82 and 83.
  • Idler roller 22 is located in jaw 32 at a point coincident with the point at which jaw 32 is pivotally mounted on the housing 18.
  • Front roller 34 (FIG. 1) mounted in jaw 30 is of the same construction as front roller 36.
  • Front roller 34 has flanges 31 and 33 freely rotatable and mounted to a shaft (not shown) like shaft 39 of front roller 36.
  • Reaction roller 62 mounted in jaw 30 between front roller 31 and idler roller 20, is of a construction the same as reaction roller 60.
  • Idler roller 20 is located in jaw 30 at a point coincident with the point at which jaw 30 is pivotally mounted on the housing 18.
  • the casing tong is lifted by a hanger 54 attached to the housing 18, the jaws 30 and 32 are opened and the bight 44 is applied around the casing 38 (having previously been set to a sufficiently large size by controlling the rams 48 and 50) and the jaws 30 and 32 are then closed and locked closed by the latch 40.
  • a back-up guy is then attached to a clevis 56 secured to the housing adjacent the rollers 24 and 26 to provide a bearing for the casing tong. If the casing 38 is to be rotated clockwise (as seen in FIG. 1) the ram 50 is extended to take up slack in the chain and is then locked in position by closing its control valves.
  • flanges 35 and 37 of front roller 36 and flanges 31 and 33 of front roller 34 all rotate freely, thereby eliminating the slippage, wear, and friction loss which result if fixed integral flanges are employed. Since the flange surfaces of freely rotating flanges do not travel at a speed faster than the speed of the casing surface, slippage is eliminated and torque is increased. In actual comparative tests, increases of 3250, 3650 and 5050 foot pounds of torque were achieved by using freely rotating flanges as compared to tests using fixed flanges on the front drive rollers.
  • Reaction rollers 60 and 62 react against the outer surface of the cylindrical member being rotated, thereby reducing the effects of the "toppling" of the casing, should toppling occur, and preventing the casing from contacting the inner edges of the jaws 30 and 32 or the inner edges of the housing 18. These reaction rollers 60 and 62 also produce an increase in torque output. In actual comparative tests, increases of 600, 2000, and 2400 foot pounds of torque were achieved by the addition of reaction rollers to a typical rotary drive apparatus.
